Members of the notorious 'Ndrangheta Italian mafia have been targeted in a simultaneous police sting in Europe.
Hundreds of police are understood to have been involved in the operation in Belgium, Italy, Germany and the Netherlands.
At least 90 people were arrested, and more than three tonnes of cocaine and 140kg of ecstasy were seized.
Italian restaurants and ice cream parlours used to launder money were among the premises raided.
Millions of euro in laundered money was seized at the businesses and homes raided across the four countries, officials said, and several "high-ranking" members of 'Ndrangheta are believed to have been among those arrested.
Eurojust - the European judicial cooperation body involved - said operation "Pollino" had been in motion since 2016.
The 'Ndrangheta mafia comes from Calabria in southern Italy. While the Sicilian Mafia was made famous in films and television, 'Ndrangheta is thought to control as much as 80% of Europe's cocaine trade, and with some 6,000 members, is a substantial and far-spread force in European crime.
